AIR NOZZLE FOR TRACK SANDERS.

Original No. 1,2l30,146, dated October 1, 1918, Serial .No. 210,922, filed lanuary 8, 1918. Application 101' I 1 reissue filed April 24, 1922. Serial No. 556,341.

To all whom it may concern:

Be it known that I, ELMER E. BRADLEY, a citizen of the United States, and a resident of Clinton, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Air Nozzles for Track Sanders, of which the following is a specification.

The invention relates to air nozzles for track sanders, that is to say for sand blowers employed for track sanding, and aims primarilyto simplify and improve the construction and operation of devices of this character, as well as to increase the efli- .ciency of the same. 1

A furtherobject of the invention is to provide a nozzle for use in connection with the sand blower of a track sanding device which is constructed in such manner as to' obviate the possibility of the air ports becoming sealed or clogged with sand or any foreign matter, thereby obviating the possibility of the sanding device being rendered inoperative.-

A still further object is to provide an injector or nozzle which is composed of a few simple, inexpensive and easily assembled parts; which is capable of being readily detached' from the trap ofthe sanding ap paratus for the purpose of cleaning or repairing; Which may be readily assembled or dismantled without the aid of special skill or tools and which will enable the sanding apparatus to be immediately 're-' sponsive upon the application of air pressure.

With these objects in view, together with Figure 4 is a side elevation illustrating the application of my invention to a 1000- motive of which a portion only is shown.

Referring now more particularly to the draw ng, 5 indicates the casingfor the ine ctor or nozzle and is provided at its ends with reduced nipples 6 and 7. These the entire length thereof. The forward end of this nozzle is enlarged and is externally threaded so as to permit the same being screwed" in'tothe bore of the nipple 7 and a jam nut lO'is threaded upon said forward end of the nozzle shank to hold the nipples are provided upon their exterior latter in proper adjusted position in the retaining nipple 7 The rear end of the nozzle is provided with a head 11; saidhead" being pointed at its rear end and formed to provide an annular forwardly facing wall or shoulder 12 at the forward end thereof. A relatively small port or opening 13 extends from the "point of the head 11 forwardly and communicates at its forward end with the larger bore 9 of the nozzle. The head 11 is alsoprovided with a plurality of angularly disposed ports" 14 which communicate at their inner ends with the bore 9 and extend forwardly and open in the forwardly facing wall or shoulder 12 of the head" of the nozzle; With the construction shown, should the small bore 13in the cone-shaped head 11 become clogged or stopped by any foreign matter,

the air, which is introduced'int'o the casing, will be permitted to pass throughthe nozzle by entering the ports 14 at the forward face or shoulder of the head 11 and thus permit the device to op'e'ratewith the same effect as it would with port 13 unclogged or open.

To enable the improved injector ornozzle' to be'a'pp'liedto the sanding apparatus of a locomotive, an internally threaded sleeve 15 is provided having an annular flange 16 I at one end adaptedto be engaged by and firmly held in position against the nipple 6 by a coupling'nut 17. It willbe understood that the threaded end of the sleeve 15 is intended to be secured to the end of a suitable air pipe or line which is indicated at 18; while the nipple 7 of easing 5, is intended to screw into a suitable trap or coupling 19, which is preferably of the four-,'

way or cross type, the upper side'or opening whereof is intended to receive a pipe or connection 20 leading from the usual sand-box 21 of the locomotive, while the the nipple 7 is provided with an outlet or discharge pipe 23 which extends to or is connected with a pipe leading to a point in proximity to the wheels of the locomotive, so as to discharge the sand on the rail at apoint adjacent to the tread of the wheel. 7 a v v In operation, thesleeve 15 is connected to the nipple 6 of the casing 5 by a nut 17 and also connected to .a suitable air line 18. Before the nipple 7 of the casing 5 is screwed into the trap or connection 19, the nozzle 8, is, screwed lengthwiseofthe casing 5 so asto-bring the forward-end in the connection 19 ,at the desired distance removed from the discharge pipe 23, to adapt the nozzle to the grade of, sand employed,

after which the jam nut 10 is screwed lengthwise of the nozzle into firm relation with the nipple 7 of the casing and the latter then screwed into the connection or trap 19 The air entering through nipple 6 and into casing 5 will pass through the ports 13 and 14 and be caused to enter the bore 9 of the nozzle and be discharged into the connection or trap 19 at a point in direct alignment with the outlet pipe 23, thereby forcing the sand through the outlet or distributing pipe. With my improved construction, any foreign matter that may become lodged against the rear end of the head 11 so as to clog the port 13 will not-interfere with the proper operation ,of the device, because the air entering casing 5 will pass through the forwardly open.- ing ports 14 and be conveyed into the main bore 9 and thus ensure proper operation of the device; while the screwing of the nozzle further into or out of the casing 5 will adapt the device either to coarse or to light san From the foregoing it is obvious that I have provided a nozzle for track sanding devices which will perform its functions perfectly and with the least possibility of being rendered inoperative. The various.

parts constituting the complete device are of simple and inexpensiveconstruction, enabling the device to be easily taken apart and assembled and any of the parts to be replaced. 4

While the disclosed construction is the preferred embodiment of my invention, it is to be understood that changes in minor details and arrangement of parts may be resorted to without departing from the spirit of'my invention.

What I claim is:

1. In a device of the class described, a

wise within the casing and secured in the outlet end thereof, a head on the' end of said nozzle and provided with ports communicating with the bore-of said nozzle,,with certain of the ports being disposed at an angle to the directionof the bore. v 3. In a device of the class described, a casing having an open end, anozzle secured in said end so, as to extend into said casing and constitute the outlet thereof, the inner end of said nozzle being providedwith a head having a forwardly facing shoulder, said head being provided with a pluralit of ports communicating with the bore 0 the nozzle, some of said ports being angularly disposed and extending rearwardly from the forwardly disposed shoulder of the nozzlehead. 1 I

4:. In a device of the class described, a casing open at the ends thereof, a nozzle projecting into said casing through one of the ends thereof and constituting the outlet, a head on the rear end of said nozzle formed to provide an angular forwardly facing wall, the bore of said head being reduced at its end, said head being provided with angularly disposed ports opening in said wall and communicating at their inner ends with the bore of said nozzle.

5. In a device of the class described, a cas-' ing having exteriorly threaded nipples at the ends thereof, one of said nipples being interiorly threaded, an exteriorly threaded nozzle adapted to screw into said last mentioned nipple, a head on the inner end of said nozzle, a nut for locking said nozzle in place, a coupling nut threaded on the other nipple, and a sleeve held by said nut and communicating with the interior of said casing.
